Pcb nixie: common questions
What microcontroller does the Pcb nixie use?
The Pcb nixie is built around the STM32L4A6RGTX, from the STM32 family.
How big is the Pcb nixie?
The Pcb nixie measures 90.7 × 90.7 mm, has 6 copper layers and is 6.956 mm thick.
How many components are on the Pcb nixie?
44 components, from 30 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the Pcb nixie design files?
From the fernandezdelpeloso/stm32-nixie-clock repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the Pcb nixie design in my own project?
The repository has no license, so all rights stay with fernandezdelpeloso. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Pcb nixie without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
